Not sure how I ended up wading into the cesspool that is this subreddit, but I'm going to weigh in here as an actual social scientist who conducts behavioral research for a living.

It's nice that you're at least trying to cite scientific evidence, but there's a lot wrong with your argument...

• Confounding variable (Social Stigma) - Every correlation you listed could be explained by the difference in social stigma attached to female partner counts -- that is, the shaming itself, which you are personally perpetuating -- rather than the actual behavior. It seems reasonable to suspect that because women are told by society to feel shame about having lots of partners, they do feel shame about it -- being bullied, belittled, and insulted does tend to lead to depression. And by the same token, because men are told by society that their significant others are shameful if they've had lots of partners, they feel shame about it, too. This

• Reverse causation /endogeneity - You didn't actually link or even name any of the specific studies you were referring to, so it's impossible for anyone except you to assess the relevance of their methodology. Without that ability, we cannot rule out the possibility of reverse causality or endogeneity. It may be that these correlations exist in part because since high partner counts carry such a negative social stigma for women, women with depression or mental issues or drug addiction would be most likely to choose that lifestyle. Since the exact same sexual behavior is considered "normal" for males, there is no disincentive (in fact, quite the opposite) for healthy, reputable men to continually increase their partner counts. That would mean there's nothing about male sexual activity that's less destructive than female sexual activity.

• Lack of Theory - Scientists make all sorts of errors when their research is driven by searching for significant results rather than by theory.
